VDEVIICE non LUBRICATING LOCOMOTIVE-AXLE JOURNALS.

Application filed November 17, 1923. Serial No. 675,282.

This invention relates to a device for the lubrication of locomotive axle journals, but more particularly has reference to devices of this description in which a solid cake of grease is employed as a lubricant.

The object of the invention is to maintain a constant supply of lubricant until the latter is exhausted, and to accomplish this without unnecessary waste of the-grease itself.

Furthermore, the invention aims to facilitate the renewal of the grease element, and to provide the cellar box which contains the lubricating elements with a door that is so constructed and reinforced that it will not break down under any force or shock such was occasionally happens from contact with the engine axle.

With these ends in view the invention consists of certain constructions and adaptation -of parts such as will be fully understood from the following description taken in con nection with the-accompanying drawings in which,latter Figure 1 is a cross section of my improvement with the parts in proper relation with respect to the axle .of a locomotive Figure 2' is an end View of the cellar box showing particularly the door of the latter Figure 3 is a longitudinal section of the construction shown at Figure 1- Figure 4 is a broken detail. section of the end of the cellar box, showing particularly the door in opened position 1 Figure 5is a broken detail side elevation of the construction shownat- Figure 4, and Figure 6 is a broken'detail side elevation showing the position of the door when the latter is closed and locked.

Similar numerals of reference denote like .50 the contour of the axle 2 and is confined by means ofthe walls of the box 1.

6 is the follower which has a concave upper face 7, and 8 is a solid grease cake whose upper face is concave to conform to the convex face of the plate 3 and whose tween the bottom of the follower 6 and the ,the grease cake, and the perforated plate upwardly so that this plate will always closely contact the axle. K

The heat from the axle during its revolution draws the grease upwardly through the perforations 4and as the grease cake wears away this wear will be compensated for by the spring urged follower 6, so that. the grease cake will be constantly kept in close contact with the plate 3.

Since this perforated plate, grease cake, and follower are all closely conformed, there can be no unnecessary waste of the grease and the latter'will always be uniformly drawn through the perforations 4.

The grease cakes are renewed from' time to time, and therefore the cellar box 1 is provided with a door for this purpose, the construction and operation of which will. now be described.

10 are the usual ears extending from op-' posite corners at the outside of the box 1 and through these ears extends a rod 11.

12 is the door proper whose lower edge rests upon and is reinforced by the floor of the box 1 when the door is in closed position, as clearly seen at Figure 3. This door has leg-like extensions 13 which depend below and are substantially flush with outer faceof the door below the lower edge thereof, and are provided with' inwardly;ex tending lugs 14 that have elongated slots 15, and the door as a whole is pivoted to the box 1 by the passing of. the rod 11 through these slots 15.

16 is a locking dog pivoted around the rod 11 adjacent to one of the lugs 14, and 17 is a coil spring around therod and confined between the other lug 14 and the dog 16,

the function .of this spring being to constantly urge the dog toward its adjacent lug, and this dog is provided with a nose'18 which, under the action of said spring, proects within the slot 15 of this lug and therey locks the door in position. Presupposing the door to be closed and locked, the parts will be in the position as shown at Figures 1, 2, 3, and 6, and it will 1 10 be observed that the lower edge of the door proper rests upon and is reinforced by the .floor of the box 1 While the lugs 14 will be in abutment against the outer lower face of the box, so that it will be clearly understood that this door is exceedingly secure in its locked position, and that any accidental shocks caused by contact of the axle with the upper edge of. the door will be sustained without any breaking down or serious damage to the door such as usually resulted when the door was afiixed t0 the box by bolts or screws.

The procedure in opening the door is as follows The locking dog 16 is forced against the action of the spring 17 until the nose 18 is withdrawn from the slot 15, and the dog is then swung rearwardly so as to bring this nose clear of the slot; the door is then pulled outwardly until the rod 11 is at the inner ends of the slots 15, whereupon the door is swung downwardly to the position shown at- Figures 4 and 5, the extreme inner ends of the lugs.14 being round as shown at 19 so that these lugs will clear the bottom of the box 1 when the door is swung open.

In closing and locking the door the latter is swung to a vertical position and then pushed inwardly until its lower edge is immediately above the floor of the box 1 so that this floor willbe embraced-by this edge and by the lugs 14. This closing of the door will leave the inner portion of the slots 15 clear, and the locking dog 14 is then swung into position so that its nose 18 will be opposite this clear portion of the adjacent slot 15, whereupon the nose 18 of the dog will be projected within this slot by the action of the spring 17, and the door will then be perfectly secure in its closed and locked position.

A swinging shutter 20 is pivoted to the front of the door, covering a peep hole 21 so that the conditions inside the cellar box may be viewed at any time without opening the door. r

22 are pins depending from the follower 6 and having eyes 23 at their ends, and when the follower is to be loaded with a fresh grease cake, it is depressed so that these eyes will pass through holes 24 in the floor of the box, and any suitable pin or other means is then inserted through the eyes so as to hold the follower in depressed condition until the grease cake is renewed. I a

What is claimed is 1. The combination with the cellar box, of-

by a slidable pivotal connection is effected nection is effected for the door, said lug engaging the box when the door is in closed position, whereby said door is prevented rom swinging.

3. The combination with a cellar box of a pivot pin secured thereto, a door having a projecting lug provided with a slot engaging said pin whereby a slidable, pivotal connection is effected for the door, said lug engaging the box when the door is in closed position whereby said door is prevented from swinging, and means for locking said lug into engagement with the box.

4. The combination with a cellar box of a door having a lug pivotally and slidably connected withthe box, 'said' lug engaging the box when the door is in closed position whereby said door is prevented from swinging, and means for locking said lug into engagement with the box.

5. The combination with a cellar box of a door having a lug secured thereto extending along a portion of the box when the door is in closed position an elongated slot in said lug, a pin secured to the box and spaced therefrom, passing through the forward end of said slot when the door is in closed position, the distance between the forward end of the slot and the inner end of the lug being greater than the distance between the pin and the box and the distance between 105.]

the inner end of the slot and the inner end of the lug being less than the distance between the pin and the box.

6. The-combination with a cellar box of a door having a lug secured thereto extending along a portion of the box when the door is in closed position, an elongated slot in said lug, a pin secured to the box and spaced therefrom, passing through the forward end of said slot when thedoor is in closed position, the distance between the forward end of the slot and, the inner end of the lug being greater than the distance between the pin and the box and the distance between f the inner end of the slot and the inner end of the lug being less than the distance be tween the pin and'the box and means for locking the lugin position when the door is closed.

In testimony whereof ll afiix my signature hereto.
